IMPROVEMENT INGAS-BRACKETS.

Specification forming part of Letters Patent No. 157,644, dated December 8, 1874; application filed November 19, 1874.

To all whom it may concern:

Be it known thatI, JAsD; SMITH, of Washington, in the county of Washington and District of Columbia, have invented certain new and useful Improvements in Gas-Brackets and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings making a part of this application.

My invention relates to a novel construction of gas-brackets, whereby one or more may be readily joined together, in order to provide light from one or more points; and it consists in providing the rear end of the tube forming the bracket with a coupling capable of continuous movement (similar to a hose-coupling motion) and having a downwardly-projectin g stem, in which is formed, interiorly, a screw-thread, adapted in size or helix to be screwed upon any stem upon which an ordinary burner may be screwed, as will be hereinaftcr more fully set forth; and my invention further consists in the peculiar construction of the rightangled arm or wall. piece of the bracket, whereby it may be cast complete, and require no ground-seat for the stop-cock, as at present constructed, as will be presently explained.

To enable those skilled in the art to more fully understand the construction and advantages of my improved gas-bracket, I will proceed to describe the same, referring by letters to the accompanying drawing,in which Figure 1 is a side elevation of a gas-bracket embodying my invention. Fig. 2 is a top View, showing the rear end coupled to a section of another bracket, the burner being removed below. Fig. 3 is a central vertical section of the coupling. Fig. 4 is a side elevation of the same, and Fig. 5 is a central section of the wall-piece.

Similar letters indicate like parts in the several views.

A represents the sections of a bracket joined together in the usual manner, having the usual burner B at the end, and, preferably, another one, O, near the rear end, having a cock, 1), to control the flow thereto. E is a similar and ordinary cock, to govern the flow of gas to the other burner, so that either one or both may be used. To the rear of the burner G, in

stem. The lower end of the coupling F is 1 furnished with an interior screw-thread, 0, adapted to screw upon any thread from which a burner may be removed. This coupling is of a conical form, and adapted to be secured in a similar ground bearing or seat, in a manner similar to the ordinary swivel-joints in brackets, and is preferably swelled at d and milled, in order to furnish a ready hold for turning the same.

In Fig. 1 I have shown the bracket secured by such a coupling to the wall-piece Gr, while in Fig. 2 I have shown the burner and disk removed from another bracket, and the coupling secured to the thread from which the burner was removed.

The wall piece or portion G, as will be seen by reference to Fig. 5, is cast solid, with the exception of the core, and is furnished at the wall end with a female thread, H, and at the other with a male thread, I, adapted to receive the coupling F;

It will be observed that the male thread I takes the place of the costly ground-joint necessary in brackets as at present constructed.

The advantages of my invention are obvious. For instance, there being but one bracket, as at present constructed, in a bed-room, light can only be obtained from one side, and in order to have it on the other also, of any fixed point, the services of a gas-fitter become necessary, as well as the extension of the supplypipe, while with my improved bracket the burner B is removed, and the coupling F secured in its place. A burner, O, is thus furnished at about the point where B was located, and another burner, B, at the extremity of the second bracket, which may be swung to any given point, and in this way any number of my improved brackets may be joined together readily without the employment of skilled labor.

It is impossible to connect two of the ordinary brackets by simply removing the burner, and they can only be extended by connecting additional arms, in an obvious manner.

PATENT OFFIGE.

My improved bracket may be advantageously applied to chandeliers, where it may be desirable at times only to spread the light.

Having described the construction and advantages of my improved bracket, what. I claim as new, and desire to secure by Letters Patent, is-- 1. In combination with the rear end of a gas-bracket, a coupling capable of continuous rotary movement, whereby the bracket may be secured to the wall-piece by the rotation of the coupling, substantially as hereinbefore set forth.

2. The coupling F, constructed substantially as described, with a vertical gas-passage terminating at its lower end in a screw-thread, and adapted to be secured to the threaded end of a pipe, in the manner set forth.

3. A gas-bracket provided with the two burners, A and B, combined with two cocks, D 1* whereby either or both burners may be used at will, substantially as and for the purpose described. Y

Witness my hand and seal.
